I'm not arguing that LTC can't be profitable. I'm arguing that LTC is vulnerable to malicious attack due to the way LTC handles mining. The fact that bot netting is profitable is the whole point.
You don't get that Bitcoin has survived for most of its life as a huge target for botnets. Botnets made a lot of $$$ off of bitcoin. If BTC can live through and even thrive with the existance botnets, then so can LTC.
ASICs will come to LTC too one day, just like Bitcoin... maybe you don't realize that. GPUs will be less profitable to mine than other ALT chains at that time, so the botnets will move to the next coin on the list, being forever forgotten in the past in LTC world.
All of your points are moot... bitcoin suffers/suffered from the same problem. You think all the botnets are already gone off the BTC network? Think again... You can still make a lot of money mining it at a high hash rate with no power costs.
LTC founding tennent is that it is Asic resistant. They changed the way mining is handled to be more "fair" and dorked with inflation. Otherwise you might as well call it bitcoin.
How can you say ASICs will come to LTC when the whole point of LTC was to prevent people from having an unfair mining advantage? Why do you support LTC in the first place then?
Yes, botnets still exist in bitcoin, but they are being pushed out of the market like I've said.
